Protocol 

A protocol is a standardized set of rules that specify how a conversation 
is to take place, including the format, timing, sequencing and/ or error 
checking. 

Roaming 

In an infrastructure network, this is when a wireless PC moves out of 
range of the previously connected access point and connects to a newly 
connected access point. Throughout the network environment where 
access point is deployed, PCs can always be connected regardless of 
where they are located or roam. 

SSID 

A Network ID unique to a network. Only clients and Access Points that 
share the same SSID are able to communicate with each other. This string 
is case-sensitive. 

Simple Network Management Protocol (SNMP) 

Simple Network Management Protocol is the network management protocol 
of TCP/IP. In SNMP, agents-which can be hardware as well as software- 
monitor the activity in the various devices on the network and 
report to the network console workstation. Control information about 
each device is maintained in a structure known as a management information 
block. 

Static IP Addressing 

A method of assigning IP addresses to clients on the network. In networks 
with Static IP address, the network ad11gstrator manually assigns an IP 
address to each computer. Once a Static IP address is assigned, a computer 
uses the same IP address every time it reboots and logs on to the 
network, unless it is manually changed. 

Temporal Key Integrity Protocol (TKIP) 

The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the 
IEEE 802.11i encryption standard for wireless LANs. TKIP is the next 
generation of WEP, the Wired Equivalency Protocol, which is used to 
secure 802.11 wireless LANs. TKIP provides per-packet key mixing, a 
message integrity check and a re-keying mechanism, thus fixing the 
flaws of WEP.
